Primary Immune Deficiency Week reminds us that immune conditions don’t always look the same. It is a reminder that when the immune system is weakened, it can also become confused. Some patients with a primary immunodeficiency not only struggle to fight infections — their immune system may mistakenly target their own cells such as platelets which can leading to ITP. Understanding this connection helps us support earlier recognition and better care.
